Yields of GM [gall midge]-resistant rices WGL 20506, WGL 23022, and WGL 16145 and cultivar Surekha following a green manure crop were examined. An early pulse crop was harvested in early Aug. The trial compared broadcasting sprouted seed and transplanting 30-d-old seedlings. Sowing was on 1 Aug and 16 Aug. Seed rate for broadcasting was 120 kg/ha, spacing for transplanting was 10 x 10 cm. Recommended fertilizer was 80-22 kg NP/ha. N was applied in three splits, all the P was applied basally. Transplanted crops yielded higher than broadcast crops. Increases were 34.7% in WGL 16145 and 30.2% in Surekha in the first planting and 16.5% in WGL 23022, 40.5% in WGL 16145, and 38.8% in Surekha in the second planting.
